A projectile is fired from the origin (at y = 0 m)as shown in the figure.The initial velocity components are vox = 940 m/s and voy = 96 m/s.The projectile reaches maximum height at point P,then it falls and strikes the ground at point Q.In the figure,the y-coordinate of point P is closest to:
A)470 m
B)45,550 m
C)45,080 m
D)940 m
E)90,160 m

The maximum height (y-coordinate of point P) can be calculated using the formula $ h = \frac{v_{oy}^2}{2g} $, where $ v_{oy} = 96 \, \text{m/s} $ and $ g = 9.8 \, \text{m/s}^2 $. This gives $ h \approx 470 \, \text{m} $.
